Shouldn't the applications doing gapless playback avoid frequent open/close of
the decoder instance too as it will add up re-instantiation (initializing hw,
allocating buffers) and cleanup (de-initialization and freeing up of buffers)
delay for each open/close respectively ? Even in case of scenario where
resolution of next stream is different than previous, I guess the application
can still hold up the file handle and do the necessary setup (stream
off/stream on/REQBUFS etc) required for re-initialization ?
